Re: WIFI_MODE_APSTA Sample

I am looking into arduino sample for esp32. There is: #define WiFiMode_t wifi_mode_t #define WIFI_OFF WIFI_MODE_NULL #define WIFI_STA WIFI_MODE_STA #define WIFI_AP WIFI_MODE_AP #define WIFI_AP_STA WIFI_MODE_APSTA So I can assume there is AccessPoint mode Station mode and AcccessPoint and Station mod...

Re: ESP32 Minimum Hardware

Schematic for minimal hardware with resistors on gpio0, and EN and buttons would be much appreciated (plan to use it with USB to logical level RX/TX adapter).
Anybody has this schematic?
